FIGURE 9 in Continuous character variation within the Glossopleura-Anoria-Sonoraspis plexus: Dolichometopid trilobites from the Cadiz Formation (Cambrian: Miaolingian, Wuliuan), California

FIGURE 9. Phylogenetic analysis of 12 dolichometopid taxa for which there are relatively complete specimens, plus two outgroup taxa. A) Strict consensus of 40 MPTs of 41 steps. B) Strict consensus of 4 MPTs of 38 steps, after removal of the less well represented taxon G. bion. C) Strict consensus of 2 MPTs of 35 steps with just 8 dolichometopid taxa, after assuming the following synonymies: G. mckeei = G. boccar; S. californica = G. mohavensis; and G. producta = G. boccar.
